Cognitive characteristics and ischemic prognosis of quantitative white matter hyperintensities in adult moyamoya disease.
Article in Communications medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhite matter hyperintensities (WMHs) are associated with long-term stroke and cognitive decline in the elderly population but differ from the young and middle-aged populations, especially for those with moyamoya disease (MMD). The aim of this study was to modify the Fazekas grade and quantitatively analyze the effects of WMHs on multiple cognitive domains and 2-year clinical ischemic events in adult MMD patients.
methodsAdult MMD patients and healthy controls were recruited for a comprehensive cognitive assessment. Among 151 adult MMD patients, the average age was 41.78 ± 10.59 years and the male-to-female ratio was 0.94. Adjusted quantitative whole-brain, periventricular (PVWMHs), and deep WMHs (DWMHs) were included in the proportional hazards model to explore their relationships with 2-year ischemic events. Linear regression analysis was used to evaluate the correlation between the WMH burden in different brain regions and various cognitive domains.
resultsMMD patients present decreases in intelligence (P = 0.000), spatial working memory (P = 0.011), verbal working memory 1 (P = 0.000) and 2 (P = 0.000), mental rotation (P = 0.008), and executive inhibition (P = 0.011). Quantitative whole-brain log
conclusionsPVWMHs have greater potential effects on verbal working memory, attention, and simple subtraction in adult MMD patients when compared with DWMHs. An increase in PVWMHs could be an indicator of future ischemic events in adults with MMD. CLINICAL REGISTRATION: Clinical registration no. ChiCTR2200058251 URL: https://www.chictr.org.cn/ .
